(Honiodoh) producing Machines; end I do declsre' the following to he s fulh clenr, end out do scription of the invention, such so will ennhle tsins to rnske and use the. some, reference being hsd to the sccoinpsnying drewin, end to'the letters of reference merited thereon, which forms pert of this speciflcstion.

My invention relutes to improvements in the reproducing sppsrstus sdspted for use in the method of recording end reproducing sounds as csrried out in thut chtss'oi? instruments known as "grsmophcnes.'

In this cless of sppsretus the record isproduced on the tune of s dish es s volute bend consisting of a. sinuous or undu'inting groove of even depth. in the production oi the rec'- ord s recording-styius is cnused to trsvel in a. straight rsdisl path from the circumference toward the center. The reproduction oi the recorded sounds is effected by giving to u reproducing-stylus e vihrstory movement icy end in accordance with the sinuosities otthe recordgroove, end these vihrstory move rnents being transmitted to n dinphrspm vibrations of the. letter give rise to sounds which are reproductions of the sounds originslly produced in the recording upperntus. in all reproducing eppsretus oi the shove type, us for us 1 nm swore, n h ngnrnr hes been employed to support the sonnd hon end stylus, and where it has heen desired to intensity the sound it horn in like nnnei' hue thereby been supported sud @fi'rTflQdg the movement imported to the erin sound-heir sud horn being ehected by, the deiicnte' groove of the record working in conjunction with the stylus. it frequently heppens thut the sinnosities of the record iesve very delicete partition-lines between the volutes of child record, so thut efter severel reproductions the grooves ere cussed to run together by the frictionof the stylus, thus'preventing scorn plete end perfect reproduction of the soundwuves recorded upon the record.

A represents e rotnting tshle which I prefer to metre of suficient weight to not es s hsl snce-wheei, so thet in conjunction with the governor the tehie-wili hove e tendency to more repnlnrly rciete'.

Upon thetelole is pieced-the dish B, contsining the record. thesnme hnving on opening in thecenter ndnpted to n thrended stern hwhich projects irons the top oi? the treble A, the record-dish heingheld in plsce hys thumbscrew Bi, which .engeges. the threuded stem h. The tehle A is secured to n verticnl sheft it which curries s pulley .dhwhich through the medium oi the heit s end pulley g imports e 'rotsry motion to the p'cvernorG.

The lower end of the shsit AT is hollowed out to receive n stntionery verticsi shuit C by which the shntt end tuhle ere supported,

end upon the lower end of the shut-tn is pinion 10 ,which meshes with as sp n u heei E,

secured to u sleeve E to which in he more nor is iestened st the iower end thereof n pinion ii. oil 'ofwhich ere su pportcd upon the stetionery verticsi shsift lit Surrounding the ststionery verticei sheit C is s sleeve h. which supports the springdrum 18" end to which the inner end oi the spring S is secured.

The sleeve 15 is provided ut the lower end to retaining-pawl j, which engages with the ratchet-wheel f to lock the latter in position during the winding of the spring. The mechanismior causing the sound-box and stylus to travel across the face of the recold is driven from the governor-el cit, in order to impart a positive and more regular motion to the stylus.

The vertical shaft G", which is driven by the pulley g, has a lower bearing in the plate F and an upper bearing in one of the brackets su porting the bar carrying the sound-box.

he governor itself, which is of very ordinary type, comprises two steel springs g and gfito which are secured the weights 9 and g. c5 At the lower end of the governor said springs are secured to a block g, which in turn is fixed tothe shaft. The opposite ends of the springs are secured to a movable block 9, to which is secured the pulley g.

n the under side of the upper portion of the cover of the machine is a leaf-spring H, having forked ends capable'of being adjusted with respect to the pulley g. The leaf-spring is pivoted at a point h, and at or neart-he center is an adjusting-screw by which the lated.

The sound-box I is carried by a short arm .1, having a spring portion j, which encircles the reduced end of the sound-boxand holds the same firmly in position. The arm. J is connected. to a sleeve J by means 0! screws j and the former acting asa fulcrum-minhwhile the latter is adapted to a slot in said arm, the object of thisarrangement being to allow for any irregularity which'ma exist between the feed imparted to the sty us by the w of the record and that given to the arm J by the mechanism acting lponthe same. l he sleeve J is mounted'upon a horizontal bar L, which is an ported at opposite ends by brackets L and L and in like manner said g brackets form supports for the screw M.: Depending from the sleeve J is an arm K,

provided with a screw is, tapered at the end,

12b engage the thread of the screw M, by which the sound-box is fed in one direction across the face of the record-disk, motion being imparted'to said screw from the shaft G by the worm g, mounted thereon, and worm-wheel m, secured to the end of the screwehaft.

One of the features of my present invention 6g. is the sound-box I, which has been desi ned tocvercome harsh a grating sounds em t it reprod ucing-diaphragms and to further reforming a part pressure of the spring upon the pulley g and consequent speed of the machine can be regnbe received with comfort by the listener.

In the present construction the sound-box I comprises a'casingorbody portion I, provided with a. reduced portion 11, through which the sound-waves are conducted.

The diaphragm I is secured to the body portion by a ring 1 and on opposite sides ofithe diaphragm between the ring and easing are soft-"rubber washers 'i;

The stylus-lever I has a heavy rigid portion to which the stylus i is secured by a secured to the ring of the sound-box by a screw 2'", there beinga under I interposed'beilgween the stylus lever and ring of the sound A delicate steel spring 1" serves to fulcrum the heavy end of the stylus-lever to the ring of the sound-box, the same being secured to the respective parts by screws 17 and i.

The volume and quality of tone emitted from the sound-box is regulated by the setscrew 1, which is threaded to the stylus-lever at the center and bears against a bufier i, fastened to the diaphragm, preferably formed ofrubber.
